There are two flavours of Fixed Wheel Brevet cards: one, as described above, is more of a booklet with space for stamps etc for about 25 events to provide evidence for claims for the Fixed Wheel Challenge requiring 25 points in Audax events on fixed. The second is a simpler card (Super Fixed Wheeler) with spaces for just the four constituent events of the SR on fixed. A particular event may be entered in both cards for the awards.
Any other queries, just PM me or use the contact details on the AUK website.
